Mg + 4 HNO3 → Mg (NO3)2 + 2 NO2 + 2 H2O - Balanced equation | Chemical Equations online! This is an oxidation-reduction (redox) reaction: Mg is a reducing agent, HNO3 is an oxidizing agent.

2018年12月14日 · To balance this equation by electron ion method. Step1: We write the redox equation in ionic form. Mg + H+ + NO3- → Mg 2+ + N2O + H2O. Step 2 : The reaction is splitted into oxidation half and reduction half reaction. Mg → Mg 2+. NO3- → N2O. Step 3: We balance the atoms of each half reaction except H and O using simple multiples. Mg → Mg 2+.
